The surface disturbance will be the removal of the vegetation, removal and/or relocation of the overburden soils, and the removal of the subsurface crystalline rock. There is virtually no vegetation in this area except a sparse growth of native grasses and a few isolated bushes, both of which their growth is limited by the lack of water. The surface soils, or overburden, is a finely divided, non- cohesive, silty soil, which varies in depth from virtually nothing to several feet. The subsurface material is des- cribed on the U.S. Geological Survey Map No. I-928, "Geology of the Sedimentary Rocks of the Morrison Quadrar..gle, Colo.", as "Crystalline Rocks of the Precambrian Period". 2. Other than visual appearance for the duration of.` the quarrying processes, there is nothing to indicate that there will be any affect on any enviromental resources. There are a few deer that habit the area, and iii spite of recent activities they appear not to be disturbed. Surface water is only that which is generated during the Spring run-off and the occasional rains. Tkiere is evidence of a few intermittent springs, which have limited flow during the spring of each year. Neither the surface water nor the spring flow will be a:~fected by the quarry operation. Several years ago two wells were drilled in the immediate vicinity, in a futile attempt to develop a source of ground water, co~zsequently, the apparent lack of sub-surface water preclude,a any possibility of disturbance of this possible resource.
